ANSWER :-

We  \: have  \: to  \: factorize =  {x}^{2}   + 7x + 12

For solving these problems we must know that we have to break 7x in two number whose multiplication gives 12 and their sum is 7x.

Now,  \\  \\  =  >  {x}^{2}  + 7x + 12 \\  \\  =  >   {x}^{2}  + 4x + 3x + 12  \\  \\  =  > x(x + 4) + 3(x + 4)  \\  \\  =  > (x + 4)(x + 3)

Hence, The Factorised form of  {x}^{2}   + 7x + 12 is (x + 4)(x + 3).
